Tuol Sleng Genocide Museum (S-21)

Between 1975 and 1979, Cambodia’s Khmer Rouge regime orchestrated a devastating genocide, leading to the deaths of approximately 1.7 million people, or about 20% of the population. In Phnom Penh, the Tuol Sleng Genocide Museum, once a high school, was transformed into a detention and torture center known as S-21. Today, the museum serves as a somber reminder of this dark period, with its exhibits including films, photographs, and artifacts that document the atrocities committed. Visitors can walk through the former classrooms, now converted into cells, and see the chilling remnants of the prison, gaining a deeper understanding of the suffering endured by the victims.
